The Physio W3+ 1.74 lens improves contrast sensitivity by helping people in day to day situations, such as driving at night, reading the newspaper and experiencing the vivid colors in a bouquet of flowers. Varilux has developed an innovative design and manufacturing process—W.A.V.E. Technology—which literally corrects progressive vision to deliver the sharpest progressive vision.
Sharp vision has two key components: Visual acuity and contrast sensitivity. By dramatically reducing or eliminating higher order aberrations, Varilux Physio delivers an improvement in contrast sensitivity—the ability to see visual details and colors--by up to 30%. Varilux Physio is the only lens proven to increase. The result is an advanced general-purpose lens that delivers unsurpassed progressive performance to all people. Bring yourself even closer to “real world” vision with optimal clarity, depth and dimension with Varilux Physio. The Varilux Physio is made by Essilor, the world's largest maker of high quality eyeglass lenses.
